within what limits a deviation of measures is allowed to accept a part

are within the tolerance set by the engineer or designer.
Mostly when we use tolerance it has a range in thousands of the unit used. If a bar is measured in 1000 mm the tolerance might be +/- 1 mm in total. Depending on what it is meant to be made for.
For example when a shaft should have a
size of 1000 +/-0.5 mm then the deviation may be at most + or - .5 mm meaning 1000.5
or 999.5. If it is more then that the shaft should be reworked until it has the correct
